Does that project do the same as this one or near to the same?

Not really. They are dealing with huge primes of form k*2^n-1, while we are dealing with all primes in one range.

Numbers in that specific form are quite easy to check for primality, therefore some really big numbers (millions of digits) are known. What PG does is trying to find all primes (not only numbers in that form) going up higher in the number space.

I hope it's clear :)

Oh, and I was really happy to hear that Riesel Project is comming BOINC :)

Hi All,

Thanks Rytis for explaining the ideas behind the Riesel Sieve Project. We're excited to try and bring the project to the BOINC platform.

Right now, we're searching for primes that are about 650,000-700,000 digits. While they may sound huge, they fall about #20 in the world in terms of size. We're trying to prove that 509203 is the smallest k where k*2^n-1 is composite for every n greater or equal than 1. Every time we find a prime, we eliminate one of the k values (right now, there's 70), and continue higher. We started in August 2003 with a total of 101 k's, and have dropped 25 through the project and 6 "externally" (non-RS contributors).

Our hope is that, by coming to BOINC, we'll be able to expand our user base (~300 users), and gain some much needed exposure.

Easiest comparison would be the Seventeen or Bust Project, where they are trying to find primes of the form k*2^n+1.

It's going to be a long way off, but I look forward to working with the BOINC community.

Thanks!
Bryan

Thanks both, thats why I asked hear as I noticed you were working with the BOINC platform and just wanted to know if the 2 projects were doing the same work or not.

Well look forward to your project coming out yet another one for me to join once you get everything going

This one appeared on dc.rieselsieve.com on Monday, Sep 01, 2008 8:54 pm.

"This is Lee. I will restore most of our severs at Riesel Sieve in the near future. 'Near Future' doesn't mean now...tomorrow...or two days from now. It may mean this weekend if I have the energy, time, and equipment/supplies to bring us back online. I regret the sudden suspension of our project with no notice. It was caused by forces outside my control and our project remained down until certain issues were taken care of. The last few weeks has only been laziness on my part and Bryan shouldn't be blamed for any of it. I look forward to restoring this project to its once former glory and I appreciate all the support and help each of you have given Riesel Sieve over the years. I apologize for the continued downtime since there is no valid reason beyond time and simple laziness for non-restoration from this point forward. I ask for patience but don't expect any...I would pretty jumpy too if I were in your place.

Look for servers to be up in the 'Near Future'

It looks like we may be getting the Riesel Sieve as a subproject.

See here

Let's hope!

Last month, PrimeGrid opened dialog with Riesel Sieve to see if we could provide any help to them. We presented a proposal to include their sieve and LLR applications here at PrimeGrid. This offer was only made as a bridge until they were able to get their servers back online.

At that time, they were not ready to accept the offer. Additionally, as Lee stated here, it is his intent to restore the "project to its once former glory..." We support this decision to restore RS. Additionally, our proposal to add their applications here at PrimeGrid remains open should they decide to accept.

We understand the eagerness of all the former RS crunchers to once again participate in the project. RS has been around for over 5 years and has established a loyal following. The collaboration between both projects has been mutually beneficial. We look forward to their return.

We will keep you informed of any developments.

How long has this project been down?

How long has this project been down?

RS BOINC has been down since the end of June. However, RS LLRNet was re-established at the end of July. Sieving is not available at this time. If you wish to run LLRNet, you can find more information here.
